On the part of Democrats, that is. Palin not only did not fall on her face, but she did a fine job. Do I wish she had more at-hand knowledge of policy issues -- of course. But she has certain qualities that are very important. Anyone who can get up on that stage against Senator Biden and hold her own the way she did -- well, I give her credit for having some real sisu (look it up, Finnish word that has no clear translation to English, but very roughly it means I WILL GET THE JOB DONE.)
David Brooks of the NYT has a very fair evaluation.
